Logging System: GDQ – 2D is a digital logging system specially designed for the convenience of field work, which can connect with various kinds of pipe and log. Because this system uses a series of advanced technology, it improves the use of one ground-based instrument controlling one heavy logging probe into one ground-based instrument controlling various kinds of logging probe, it also includes the deep measurement, the power supply and so on. The instrument has a light weight and simple operation and maintenance, which can be connected to the tube type, which can be aseismatic, temperature-resistant, moisture-proof and high reliability. Description: GDQ – 2D integrated digital control logging system is a new generation of digital logging equipment., which based on summarizing more than 20 years in production and successful experience of digital logging equipment’s research and development, following the international new trend of development of the small digital logging technology, and combining with China’s national conditions. This set of equipment has the following advantages over other similar products: (1) the measurement parameters are large and the scope is wide. (2) the reliability is high and the Mean Time Between Failure (MTBF) is long. (3) portable, convenient for mobile transportation. (4) operating and maintenance is simple. The main reason for these advantages is that the design and development is absorbing other’s merits, fully considering the various needs of the industry, and considering the competitiveness in the international market. GDQ – 2D system can measure than 20 kinds parameters, covered with metal ore, coal, oil field, radioactive, hydrology, and other areas of the various user’s requirements, with great cost-effective. Parameters: 1. The use of the environment:Power supply: 220V, 50 Hz;Using the environment temperature: -20℃ ~ 45℃;Using the environment humidity: 90% or less (45℃) 2.The depth measurement system:Depth measurement range: 0 ~ 9999.99 m;Depth resolution: 0.28 mm;Speed measurement range: 0 ~ 9999m/h;Deep optical pulse signal: 3600 pulses per meter 3.Signal transmission system: Bottom hole output signal: bipolar coding;Communication with the computer: RS232 or USB;The underground signal detection level: plus or minus 0.5 V ~ plus or minus 12V 4. Figure out the depth of the graph; 1:10; 1:50. 1:100. 1:0; 1, 50, 0, etc. 5. The drawing accuracy:8 points per millimeter (curve);64 pixels per square millimeter (image method).
